Usage:
|
||||
scripts/build-android-libyuv.sh [options]
|
||||
|
||||
Options:
|
||||
--source <dir> Existing libyuv source checkout. If omitted, the script
|
||||
clones libyuv into .tmp/android-libyuv-src.
|
||||
--output <dir> Output root. Default: dist/android-libyuv
|
||||
--ndk <dir> Android NDK root. Defaults to ANDROID_NDK_HOME or ANDROID_NDK_ROOT.
|
||||
--api <level> Android API level. Default: 21.
|
||||
--abis <list> Space/comma separated ABI list. Default: arm64-v8a armeabi-v7a.
|
||||
--jpeg-root <dir> Android libjpeg root. Defaults to ONE_KVM_ANDROID_TURBOJPEG_ROOT
|
||||
or dist/android-turbojpeg when present. Enables libyuv HAVE_JPEG.
|
||||
-h, --help Show this help.
|
||||
|
||||
The output layout is compatible with ONE_KVM_ANDROID_LIBYUV_ROOT:
|
||||
<output>/arm64-v8a/include
|
||||
<output>/arm64-v8a/lib/libyuv.a
|
||||
<output>/armeabi-v7a/include
|
||||
<output>/armeabi-v7a/lib/libyuv.a
|
||||
|
||||
Example:
|
||||
scripts/build-android-libyuv.sh --output /opt/one-kvm/android-libyuv
|
||||
|
||||
export ONE_KVM_ANDROID_LIBYUV_ROOT=/opt/one-kvm/android-libyuv
